I have added two domains to cloudfare. For the first one everything seems to have worked out well.
I have added my second domain to cloudflare. Then I accepted the entries that were offered to me under DNS management. Two hours later my website was no longer accessible. I received 200 entries under DNS management. To me it seems as if DNS management had added all sorts of directories from Wordpress.
Thank you jake1st for your response. How do I know which entries I need for sure? On the site where it worked there were only four entries. (I can add a screenshot tomorrow).
I saw few similar topics, and I belive this could be due to a possibility if you have had an asterix * in the DNS zone at your ex hosting provider, so when Cloudflare scanned it, it added all of them in alphabetical order word (somehow happens, not sure exactly).
